ABOUT THE TIGERACCESS EE SWITCH

VDSL can deliver high-performance online applications, such as high-quality video and other switched multimedia services. This Ethernet-over-VDSL system provides robust performance, with a maximum symmetric data rate of 100 Mbps for runs up to 200 meters (656 ft). This system is based on advanced VDSL2 Multi-Carrier Modulation (MCM) technology with adaptive channel equalization that overcomes bridge taps and other line distortions. Reed-Solomon Forward Error Correction and interleaving protect against errors due to impulse noise and enable recovery from signal interruptions. Frequency Division Duplexing (FDD) separates downstream and upstream channels and allows VDSL signals to coexist with regular telephone services. A power back-off mechanism is also implemented to reduce noise from crosstalk in line bundles.

Switch Architecture

The VDSL Switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

For communications between different VLANs, this switch uses IP routing. For communications within the same VLAN, the switch uses store-and-forward switching to ensure maximum data integrity. With store-and-forward switching, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.

Network Management Options

This switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of network and port status. It also includes a management agent that allows you to configure or monitor the switch using its embedded management software, or via SNMP applications. To manage the switch, you can make a direct connection to the console port (out-of-band), or you can manage the switch through a network
